AH] I I Q lN-VENTOR ATJ'ORN EY QZWD UNITED STATES. PATENT-OFFICE Y anmusnnussniuor s1. caoiix FALLS, Wisconsin-Q I To all whom it may concern:

l 3e it "known that I, JULIUS Hnussnn, a citizen of the United States, residingat St;

Croix Falls, in the county-of Polk and State 7 of Wisconsin, have invented certain new and useful Improvementsin Chair Attachments,

of which the following is a specification.

' This invention relates to furniture, andmore 'especially to book holderswhich are supported at their base and are adjustable; and the object of the same is to produce an attachment to an ordinary chair by means ofwhichthe occupant thereof may support a book or the like in front of him, or a table or stand which isadjustable, and by means;

of which he may change the positionof said tableso as to do writing thereonr a I A further object is to improve the details of construction of such a device so as to facilitate the adjustment of parts and amplify the uses of the whole. v

Details are brought out in the following specification, and reference'is madeto the drawings, wherein F'gure 1 is a side elevation of an ordinary Morris chair with this attachment applied holders, 7 K

The ty e trchair to which this attachmentfis applied. isnot essential, excepting that it is most convenient that it shall have 5 armsherein designated by the numeral 1..

' Specification of Letters Patent.

Pivotedat- 5 between the" fork-arms the:

base 6 of a support 7 which: is of U-shaped cross section as best seen in Fig- 4,'and thisbase is provided With abolt 8-1which moves in arcuate slots 9 struck :in-the fork-arms 4L. around the pivot'bolt 5, whilean appropri I ate tightening device l0 is located' on one' end of the bolt '8 i so that after the 'biLSQThELS been adjusted to the proper angle it may be clamped betweenthe armsla 'by manipulate ing said tightening devicelin; almannenwhichwill be clear. .Above the fork the support .7 is of U-shaped section as has been stated, and slidably mounted thereon is a runner 11 which is also of U-shaped cross section a ratentease eea, 19 s; 'Ap plicationfile d rebruaryarisls. seria1n 2ia525. 7 a

with fingers12hooked around the backof I the support so that these two elements may not become disconnected although the runner mayslide on the support. Pivoted at 13 to the upper endwof each. runner is a hanger plate 14: whose configuration is -best seen in Fig. 7, a'ndtin the body of-this'v plate is an arcuate slot .15 which moves'on-a stud,

' bolt 16 carriedby thelower end oftherunner as seen'in Fig.- 5-." A tighteningjfdevice 17 is mounted also on thestud bolt inside the plate-I L and; outsideja .pin 18 through the inner end-of the bolt, andthis device also may be of any appropriateconstruction.

I might heresaythat the'tightening devices herein illustrated'are composed of spiral; V.

cams rotatably'mounted on the bolts which support them and 'havi n radial arms by which theymay be turnefl H on said support tomove their bodies longitudinally on the bolts and tighten the members carriedcthere;

arcuate's'lot 15 in the hanger plate is'quite ample and the result isthat'the parts carby;',but it is obviousthat-other forms'ofg. tightening devices may be employed, ;The{

ried therebymayibe swung for a consider-' V able distance around the pivot'l3 ;and/the adjustment permitted may beujsedin' addition 5 to the; adjustment of the ;;support '1 around its pivot'5, or not, as preferred. Q

As an addition or refinement, I may use at the lower endof each runner between and the hanger plate a brake element con-* sisting' of a right-angularmember whose body-19 is slidably mountedon the stud-bolt 16 and whose foot -2O constitutes a shoe adapted to*bear against theisupport T and frictionally' sustain the partsjin their; ad- 7 justed position; and :this brake isheld in Contact with the.

. 1 plate-14 by thesame tight 7 Mounted on the bolt 13 at the upper end ing directly toward the corresponding long leaves at the other side of the attachment and being slotted as at 24. These long leaves are slidably mounted in channel bars 25 secured to the bottom of two panels 26 of which the book-rest or table top is made up, and where they meet at the center of the same they may well be hinged at 27 so as to connect their channels. Set screws 28 pass through the slots 24 and through the bars and into the panels, to permit adjustment of parts. By this construction it is obvious that if the arms 1 of the chair are quite far apart the long leaves will he slid outward in the channel-bars, and vice versa, and therefore the attachment is applicable to a wide variety of chairs now on the market. By loosening the tightening device 10 at each side, the support 7 may be adjusted angularly with relation to the forks 4, and therefore the entire device may be tilted from the reader or swung up toward him, or might in fact be let clear down to almost a horizontal position as seen in Fig. 11 in case he desires to use the device for writing purposes. By loosening the tightening device 17, the angle of the book-rest or table to the support can be adjusted in a manner which will be clear, and this adjustment is independent of the adjustment of the support within the fork. At any time when the attachment is not desired on the chair, the shanks 3 of said forks are pulled out of the sockets 2, this entire device folded into a small compass, and laid away. 1

I prefer to make the table top in what might be called a boX shape as perhaps best seen in Figs. 4: and 9, and the panels 26 referred to above constitute the bottom of this box. The top of the box-like table may well be in two shallow sections 30 hinged at 31 to the upper ends of the panels and adapted to fold down over them, and the sections will have surrounding flanges 32 which eventually form the walls of the box-like top. The panels 26 may have upstanding flanges, shown in Fig. 9 at the left as surrounding one panel at the right and sub-dividing the other into compartments, and numbered respectively 33 and 3% Rising from the upper sections 30 near their lower edges are ledges- 35 for supporting books and the like when the table stands practically upright. An ink-well support (see Fig. 6) may be employed, here shown as consisting of a ring 36 and a link 37 by means of which it is connected to the table so that it may'overlie the same as seen in Figs. 2 and 11, or be folded under the same as seen in Figs. 1 and 8. Finally a cord 38 having knots 39 is attached at one end at the point 40 to one edge of the table as seen in Fig. 2, led over the same so as to hold the leaves of the books open, and passed at the other side of the table through a fork 4:1 whose arms are spaced to receive the cord but not to permit the passage of the knots.

An amplification of which the device is susceptible is shown in Fig. 10. This consists ofthe use of a leg 14 having a caster or other form of a foot so at its lower end, its upper end being adjusta-bly mounted through an eye a6 in a rigid arm 47 which is preferably square in cross section and is passed through a hole $8 in either one of the arms 45 of the fork, somewhat in rear of the arcuate slots therein. A setscrew 4:9 serves the purpose of permitting vertical adjustment of the leg within the eye 416.

The leg obviously passes down outside the chair arm but its caster or foot 15 will not rest on the floor in this position, as still the chair attachment with the leg attached will rest on shanks 3 on the chair arms, when the chair attachment is in use for reading or writing purposes, If, however, the occu pant desires to leave the chair, then he can pull out shank 3 on the side to which the leg attachment is mounted to the arms at of the fork and set the attached leg with the caster or foot 45 on the floor. In this position the chair attachment resting with one support 7 and its members on the leg, can be moved on said leg around its pivot, said pivot is the other shank 3 which still remains in the other chair arm.

This leg attachment will merely be used for invalids, as normal users easily can leave the chair by pulling out one of the two shanks 8, turning the chair attachment outward around the other shank as its pivot, and then turning back the attachment and replacing shank 3 in its base. In this manner the normal user can occupy or. leave the chair at any desired moment, without using the leg attachment, or take the chair attachment from the'chair and without taking the load from the table. All parts of this device are of the desired sizes, proportions and materials, and by preference they are ornamented appropriately so that the attachment will be an addition to the piece of furniture to which it is applied.
